Abstract: A device for dispensing a metered amount of powdered, granular liquid or related fluent materials and a method of dispensing a fluent material such that a release of excess material beyond the metered amount is inhibited. The dispenser includes a sealing arrangement to effect such inhibiting, as well as to reduce moisture-based contamination of the material stored within the dispenser. Optional features may include various seal configurations and numbers, removable top and bottom caps that both may have a locking mechanism. The dispenser may be configured as a disposable hand-held device such that, after depletion of the fluent material contents arising out of a multiplicity of uses, it can be thrown away.
